yTo all' "itmll/ Concern:

Beit known that I, JACOB FELBEL, a citi` "l'zen `of thegUnited States, and resident of the ,bongh.' of Manhattan, city of-New York, f linheeollnty ofNew York and State of New York, lhavei'nvented certain new and nseful Improvements in TypeWritng Machines',` of,which 'the `following is a specificaif tion.

Myfinvention relatesto typewriting machines, and-.more particularlyoto typebar supports or rests, and has for its object thev provision :of atype lbar rest which will tend to absorb the shock of the type bars as they are restoredl to normal position, "thereby reducing'. orV preventing the rebound, of the l type bars and preventing the adj ace-nt bars from clashing near thetype-bar support or basket. Y

` Tol the' above and other ends which will f'hereinafter appear, Vmy invention consists in the eatures of construction, arrangements of parts and combinations. of devices to be described in thegfollowing specification 4and f, claims.

particularly pointed out in the appended In the accompanyingdrawings, wherein like reference characters indicate corre- `sp'onding parts in thevarious views, Figure l lis. a.' fragmentary central vertical sectional view of' a typewriting machine embodying my invention. Fig. 2 is a detail plan view i l of the `type barsegment, the type bar rest and its connectiony with the ytype barsegment. Fig. 3 is an enlarged detail fragmentary side elevation,partly`in section,of one of the devicesfor connecting a type bar support vto the type barY segment. Fig. 4 is a lfront elevation of the type bar support and the type bar seg ent to which it is secured, three of they type ars vbeing shown in this view.

i` The `frame of th'exm'achine comprises" a yl `basel,"cornerposts 2 and a top plate 3. The

\ platenfl, diagrammatically shown in Fig. 1,

is supported by Ia carriage on the top plate in the usual e manner and is `adapted to travel from side to side 'of the machine.V Type bars 5 are pivoted at 6 tota type bar segment? and are segmentally arranged and adapted to move upwardly and rearwardly to the printing point. 'Each type bar is connected to a restoring spring 8 anda forwardly extending link is pivoted to each type bar at 9, the rear end of the link being .pivo'tedfA aft 10 toan upright sub-lever 11 plvotedat 12 to ankey lever 13. The key levers are pivotedffat 14 to the base of the machine andare provided with finger keys 15 and restoring springs 16. Each of the sub-levers 11 is slotted at its lower end portion as at 17 for cooperation with a fixed 'fulcrum rod 18 which extends beneath the key levers and is attached at its ends to the base of the machine. The type bar. segment is preferably 20, the latter being likewise received in' grooved guides 21 secured to the base1 ,'ot the vmachine at each side of the segment Forwardly extending arms or rods 22 project from the type bar segment and `eachhas one member of the universal joint `connectedr thereto at its fdrward end. Inltlie present instance `the universal joints are in the form of ballv and socket '"joints, each'socket me1nb er being formed by two plates 23 secured together and to the ,arm 22 which carries :it by a bolt 24 which extends through openings in the two members 23 and in the forward end, arm or rod 22 and is secured Ain place by a nut 24a. The ball member 25 which coperates with the associated socket is formed on the rear end ,of a. link 26,-the forward end of said link being pivoted to a type rest by a vertically disposed bolt' 27 which extends through perforations in rearwardly extending lugs 28 formed on the type Y. bar rest 29. Each nut 24 connects onend Thuseach end olf.

of a leaf spring 30 to the associated sogket member of the universal joint, the freeheind of the spring being bent upwardly and extending beneath the associatedl link 2G. to`

support the link and type rest or basket in'y the normal position. The ltype rest 29 preferably` a rigid segmental bar carrying a' suitable pad 31 on Which'the forward or free ends ofthe typebars rest.

From an inspection of Fig. .2 it will be seen that the links 26 are in the nature of' parallel links and that the universal joints by which' the links are-connected to the segr ment, or to the arms 22 projecting therefrom, afford a movement of the type bar suppprt in any direction and that the leaf springs 30 are suiiiciently wide to afford a movement of the type bar support veither to the vright or left for a considerable distance without displacing the links from'- the springs.

The construction is such that the spring Supported type bar support will absorb the shock of the type bars as they are restored to. normal position no matter in what direction the. impact is Vreceivedfrom the type A bars striking against the type Vbar support.

will be understood furthermore -that th system of segmentally arranged type bars normally resting in the basket or against the type bar support, tends to maintain it in the normal position andV that the shock or impact of a returning bar tends to displace the type b ar support against the pressure of one o r both o the springs 30, inasmuch as thennpact is always. received in a general downward direction. When one of the type bars at one side of the segment im- -pacts against the type basket, the type bars at the other side of the system tend to prevent a material displacement of the type basket in the direction of the blow,although a ydownward movement of the type basket against the tension of one or both of the springs 30 may take place. Thus from an examination of Fig. 4:, it will be seen that if the left-hand type bar f shown in saidv figure impacts against the type bar support -.thetype bars at the opposite'side, of the segmenuwill tend to resist a movement of the typeI rest as a whole toward the left,

but that a slight downward movement of the type bar rest against the tension of.one or both of the springs 30 is effected by the impact of the returning type bar. An impact of the center type bars against the type bar .support or rest will be equally distributed 2. A spring supported type rest connected t'o its carrier by a universal joint'.
